MECHANISM FOR ATTACHING SIGHTING-TELESCOPES TO FIREARMS.

Specification of Letters Patent.

Patented June 29, 1915.

Application filed June 2, 1914. Serial N 0. 842,390.

To all whom it may concern:

Be it known that TERJE AANENSEN FIDJE- LAND, late a subject of the King of Norway, and a resident of Fostvedt, Iveland, pr. Christianssand S., Norway, but now deceased, did invent a certain new and useful Improvement in Mechanism for Attaching Sighting-Telescopes to Firearms, (for which patent has been obtained in Norway, No. 24,608, application filed 3d June, 1913), of which the following is a full, clear, and exact specification.

The present invention has for its object to provide a mechanism for releasably attaching sighting telescopes to fire arms.

The invention is illustrated in the accompanying drawing in which:

Figure 1 is an elevation of the attachingmechanism, partly in section. Fig. 2 is a corresponding view but showing the parts in a different position, and Fig. 3 is an underside-view of the attaching-mechanism.

The barrel of the fire-arm is indicated at 1, and 2 represents the telescope tube. Between both these parts a rigid but simultaneously readily releasable connection is to be established. For this purpose a holder 3 is cast to, milled out in or especially attached to the barrel 1. The holder has parallel sides and is provided with end noses 4-, the outer side of which inclines against the barrel and are rounded in order to prevent side-rattling as more fully explained hereinafter. On the telescope is attached a block -5 having also parallel sides and having rearwardly a down-projecting nose 6, the foremost inclination and rounding of which corresponds exactly to those of the rear holdernose -4. The block 5 has further a longitudinal channel 8 for an exactly fitting piston 9-, from which a front nose 7 projects downward. The said nose has an inclination and a rounding quite corresponding to those of the front holdernose 4. The piston -9 has further a bore 10 which is open in front and in the innermost part of which is placed a helical spring 11 and in the outer part a pin 12 pressed by the spring against the inner side of the foremost portion 13 of the block. The pin thereby tends to force the whole piston 9 backward, until its 0&- set 14 stops against the rear face -15 of the opening through which the nose -7 projects. When the piston is to be taken out the block 5 is released from the holder 3 and from the down-projecting holding part 16- of the telescope tube 2. The said holding part forms the upper side on the piston channel which therefore now is open at its upper side and also, by the opening 17, partly at its under side. The whole piston consequently can easily be turned into an inclined position and be pulled out through the said opening in downward direction.

As shown in Fig. 1 each of the noses 6 and 7 on the block 5 catch down upon a holder nose 4- and thereby hold the telescope safely fast to the fire arm. On account of all noses being rounded all rattling of the telescopewhich in other cases would occur, for instance by the use of guides parallel to in the axial direction of the telescope-is completely dispensed with, because the spring bolt 12 will always cause the noses to be in tight engagement in a definite position, no extra measures being thus required in order to prevent rattling.

By making the spring 11- sufficiently strong the telescope will be held immovably in its position, but nevertheless it may be easily removed and put in the pocket. The removal is effected by pulling the telescope somewhat back so that the rear nose 6- passes clear of the corresponding holdernose 4 (see Fig. 2), whereafterthe whole telescope with the block 5 can be removed from the holder 3-. The telescope may also be released by a rapid jerk, whereby its rear or front end is moved out from the barrel or the holder. How the telescope is again mounted in position will be understood without further explanation.

The easy releasing and mounting of the telescope is advantageous in many cases, not only in war guns but also in sportsmens rifles. For instance by removing the telescope the arm may be made useless for sighting and thus its utility for persons not concerned or for the enemy in war may be partly destroyed.

Having now described the invention,what I claim as new and desire to secure by Letters Patent is:

1. In a device of the class described, in combination, a fire arm, a telescope, and means releasably attaching said telescope to said firearm, said means comprising a member mounted upon the firearm, a second member carried by the first member and including two parts, one of the parts of the second member being movable in a longitudinal direction, and a spring normally holding said movable part in its operative position.

2. In a device of the class described, in combination, a firearm, a telescope, and means releasably attaching said telescope to said firearm, said means comprising an inclined member mounted upon the firearm, a second member carried by the first member and including two parts, the second member being inclined in a direction opposite to the inclination of the first member, one of the parts of the second member being movable in a longitudinal direction, and a spring normally holding said movable part in its operative position.

3. In a device of the class described, in combination, a firearm, a telescope, and means releasably attaching said telescope to said firearm, said means comprising coacting, inclined, rounded members, one of the members including two relatively movable parts one member being inclined in a direction opposite to the inclination of the other member, and a spring normally holding the relatively movable parts of said member in operative position.

4. In a device of the class described, in combination, a fire arm, a telescope, a holder on the fire arm having rounded, undercut ends, and means operatively connected to said telescope having a fixed nose adapted to engage one end of said holder, and a spring pressed movable nose adapted to engage the other end of said holder, whereby said telescope may be releasably attached to said stems? 5. In a device of the class described, in combination, a fire arm, a telescope, a holder on the fire arm having rounded, undercut ends, a recessed block operatively connected to said telescope and having a fixed nose adapted to engage one end of said holder, a piston in the recess in said block provided with a nose adapted to engage the other end of said holder, said piston being movable whereby it may be moved into and out of its operative position, and a springnormally holding said piston in its operative position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
